| Abstract: | The infrared and Raman spectra of UO2(salen)(H2O)] and UO2(salen)(CH3OH)] (salen=N,N′-ethylenebis(salicylideneimine) have been recorded. Assignments for the fundamental vibrations are proposed on the basis of C2v symmetry for the former species and Cs for the latter. The calculated values of the stretching force constant of the uranyl group, FUO, are 6.87 and 6.63 mdyn Å?1 for UO2(salen)(H2O)] and UO2(salen)(CH3OH)], respectively. The corresponding values of the UO bond lengths calculated as 1.738 and 1.745 Å. |
